specification.

The present invention relates to improvements in explosive enginetractors, the primary object of the invention being the provision of a,two-wheeled tractor, provided with draft attaching means, whereby thetongue of a wagon or farm implement may be connected thereto the wagonor farm implement constituting a means for preventing the over-balancingof the tractor, and itself being hauled by the tractor similarly to thedraft animals, the present construction thus providing a means wherebythe use of a tractor for hauling and farming purposes is morepractically effected, as the length of the complete apparatus isreduced, and the tractor is manipulated so as to be steered and turnedin a shorterspace, than is the usual practice when a three or four wheeltractor is employed.

A further object of the resent invention is the provision of a noveframe and connecting means, for a two-wheel explosive engine tractor,whereby the implement to be hauled is readily attached'thereto through-,the medium of its tongue or shaft, the

tractor frame being provided with auxiliary means" for maintainingthesame against over-balancing when disconnected from the implement, orwith a trailing support for connection thereto during transportation ofthe tractor.

With the foregoing .and. other objects in view which will appear asthe-description proceeds, the invention resides in the combination andarrangement of parts and in the details of, construction hereinafterdescribed and claimed it being understood that changes in the preciseembodiment of the invention herein d1sclosed can be made with in'thescope of what is claimed without departing from the spirit of theinvention.

In the drawings F igure 1 is a top plan view'of the complete tractorattached to a corn planter. Fig. 2 is a side elevation thereof. Fig. '3is a top plan view of the auxiliary supporting structure for the rearend of the tractor frame. F igx l is t beam 10.

design. rearwardly and carries the pinion 22 which plan view of the seatand supporting member thereof.

Referring to the drawings, the numeral 1 designates the twotractorwheels, which are ,mounted rotatably upon the axle 2, said axle plosiyeengine-E, which is disposed transversely of the frame, in the mosteffective manner. A center support 4 is provided and has upstanding,therefrom, a post or standard 5, which constitutes the pivotingelementfor the axle, which is inreality the steering axle of the tractor. Thedivergingv brackets 7 are connected to the up-per'end' of the post 5 andsupport the upper end of the radiator frame 7 which is supported' frombelow by the engine platform'3.

Connected to the rear end of the frame 3 is the steering toothed segment8, while extending from the under side thereof, and y from the axlerearwardly is the longitudinal beam 9, which is braced from the upperend of the post 5 by the downwardly inclined A vertical rod or post 11is mounted for rotation between the beams 9 and 10 tothe rear of thetoothed segment 8, and carries upon its lower end the pinion 12 in meshwith the teeth of thesegment 8, and the horizontalworm gear 13,WlllChJS'lIl mesh at all times with the worm 14 carried by the inclinedshaft 15, said shaft 15 beingjiournaled for rotation in the supportingseeve 16 carried by the brace l The forward end of the beams 9 and 10 arethus pivotally connected to the post 5,

which constitutesin reality the steering post or king bolt connection ofthe tractor axle 2 to the remaining part of the machine.

The engine shaft 17 is provided with a pinion. 18, which is in mesh withthe pin ion 19 of the rearwardly extending horizontal shaft of thetransmission and control mechanism 20, which is of any desired The shaft21 thereof is extended engages the differential. gearing 23 connected.to the driving shaft 24 which as shown in Fig; 1, is journaledtransversely of the frame 3 at the rearvof the axle 2, and

carries upon its extreme end the driving pinions' 25 which are in meshat all times with the large gears 26 keyed to and rotatable with thetractor wheels 1. By this means the'engine B will rotate the tractorsand the control thereof will be directly under the operator, as willpresently appear.

The engine E is so disposed that upon the opposite end of the shaft 17may be mounted. a drive wheel (not shown), whereby the engine may beused for sawing or other farm purposes when in a stationary position,when desired.

. The universal joint 27 connects the shaft 15 to the telescopicsteering shaft 28,.which as shown in Fig. 2 is extended rearwardly andhas connected thereto'in ready access to the operator, the steeringwheel 29. The shaft 28 is made telescopic, so that the same may beshortened or lengthened, while the universal joint 27 is provided topermit of the lowering or raising of the telescopic shaft 28 sons tobring the steering wheel -29 in-.ready position to the operator.

A frame 30 is connected to the under side of the beam 9 and thetransversely disposed shaft constitutes the pivoting point for therearwardly extending and converging arms 31, whose rear free ends carrythe lower rotatable end of the adjusting screw 32, said adjusting screw32 being connected by the usual nut structure in the frame 33, so thatthe screw may be rotated to raise or lower the rear end of the beam 9relatively to the supporting frame 31.

' An upstanding bail shaped frame 34 is carried adjacent to the rear endof the beam 9 and provides a means for adjustably supporting thetelescopic frame 35, whose forward end is connected to the forward endof the frame 30, while the rear end extends rearwardly to support thestandard 36 'which carries the shaft to which the clutch operating lever37 and the engine control lever 38 is connected. By means of theadjustable connection of the telescopic frame to the frame 34, thelevers 38 and 37 may be adjusted vertically to be placed in the desiredposition for manipulation.

Connected to the respective levers 37 and 38, are the forwardlyextending telescopic connecting rods 39 and 40, which have their forwardends connected to'the respective clutch control bell crank lever 42 andthe engine control lever 43, both of which levers are carried by thebracket 41, as clearly illustrated in Fig. 2. Thus the controlof theengine, is placed in easy reach of the operator, the said levers 37 and38 and the steering wheel 29 being placed so that all may be readilyoperated to control the steering of the tractors 1, and the control ofthe engine, both as to speed, and forward and reverse movements.

In order to provide a means to prevent the forward end of the frame 3from tilting or overbalancing the frame 9 and 10,

' tractor so when the same is, disconnected from the corn planter 59, orthe sulky as shown in Fig- 3, an arm 44 is swingingly connected to theunder side of the forward end of the frame 3 and is disposed to befolded as shown in full linesor extended as shown in dotted linesthrough the medium of the collapsible brace 45, the fork 46 beingcarried in the lower end of the arm 44 and having journaled therein, thecaster wheel 47, which normally assumes a full line position, as shownin Fig. 2, but may be extended to engage the ground, as shown in dottedline position to thus properly support the for-,

ward end of the frame as described.

The supporting members 48 of the frame 3 which are connected to the axle2, when the tractor is supported upon the sulky, as shown in Fig. 3,receive the aper'turedends 49 of the cross rods 50, the rear ends ofsuch cross rods being connected to the axle 51 of such sulky and havejournaledithereon the wheels 52. The converging arms 53, which areconnected to the casing 55, are disposed to receive the rear end of thearm 31'when the sulky is in engagement with the tractor, and have theirforward ends 54 apertured and connected to the transverse'rod thusproperly connecting the sulky wheels to the that the rear end of theframe may be properly supported. The seat 58 is carried by the curvedsupport 59 which is properlyconnected to the beam at 60' and 61 topermit the operator ready access to the steering wheel 29 and thecontrol levers 37 and 3 8. This sulky is only employed when the tractoris being moved from place to place.

When a corn planter and other farming implement as C is connected to thetractor, the same supports the rearend of the frame 9 as illustrated inFig. 2, and has its tongue 60 disposed below the beam 9 and connected atits forward end by means of the attaching eye 61, while the plate 62thereof engages the extreme ends of the arms 3l,'thus connecting thecorn planter so that the same will support the rear end of the tractor,and without the necessity of cutting the tongue as is the usual practicein attaching farming implements to a tractor. By'this means the operatormay sit in the proper position for operating the planter or otherimplement, and atthe same time have under full control the steering ofthe tractor and the operation of the engine. What is claimed is:

1. A two wheeled explosive engine tractor, including an axle, a framecarried by the axle, two tractor wheels rotatable upon the axle, a postforming a pivoting element for the axle and wheels carried by the frame,a longitudinal beam extending rcarwardly from the frame, an inclinedbeam connected pivotally to the upper end of the post and having its.rear end connected to the rear end of the longitudinal beam, a pair ofarms swingingly connected below and at the free end of the longitudinalbeam, and an adjusting screw mounted in the rear end of the longitudinalbeam and the free ends of the pair of arms to regulate the position ofthe arms relatively to the beam.

:2. A two wheeled explosive engine tractor, including-an axle, a framecarried by the axle, two tractor Wheels rotatable upon the axle, a postforming a pivoting element for the axle and wheels carried by the frame,a longitudinal beam extending rearwardly from the frame, an inclinedbeam connected pivotally to the upper end of the post and having itsrear end connected to the rear end of the longitudinal beam, a palr ofarms swmgmgly connected below and at the free end of the longitudinalbeam, an adjusting screw mounted in the rear end of the longitudinalbeam and the free endsof the pair of armsto regulate the position of thearms relatively to the beam, and a hook connected to the under side ofthe longitudinal beam adjacent the axle, whereby the forward end of thetongue of an implement may be connected thereto while the free ends ofthe pair of arins engage the upper portion of the tongue adjacent theframe of such implement.

In testimony thatI claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.
